Mr Zhou is one part of the nine-man politburo Standing Committee and is responsible for maintaining law and order in the country. He recently suggested that the government create a centralised data-base of Chinese citizens, and use it to collect and record information, an idea with which scary comparisons can be drawn to the citizen surveillance policies of Nazi Germany.
China's autocratic ruling party has been worried by recent protests in the Middle-East and North Africa, fearing a similar eruption could occur in China and threaten Communist rule if not supressed quickly and forcefully.
